Description

The invention relates to a roof window device for mounting in an opening provided for a roof window, a roof window arrangement with such a roof window device and a method for installing such a roof window device.

When installing a skylight, an opening is usually provided on the roof into which the skylight is installed. The conventional assembly of a roof window requires several employees, whereby when renovating a roof window, the roof window must first be dismantled, i.e. the roof window is removed from the roof window frame. The roof window frame is then inserted into the opening by several employees and held in the appropriate position until the roof window frame is screwed to the roof from the outside by an employee. Even when building a new building or retrofitting a roof with a skylight, several employees are required to insert and align the new skylight.

It is therefore the object of the invention to provide a roof window device, a roof window arrangement and a method for mounting such a roof window device in a skylight opening, in which a roof window device can be pre-assembled in the roof window opening without tools and / or without additional assembly aid.

This task is solved with the features of claims 1, 10 and 12. Advantageous refinements are the subject of the subclaims.

According to claim 1, a roof window device is provided for mounting in an opening provided for a roof window. The roof window device has the following: a frame element, a window mounted or mountable in the frame element, and a holding device with a first holding element and a second holding element, the first and second holding elements being arranged on the frame element in an extendable and/or pivotable manner, and by pivoting out and / or extending the first and second holding elements, the width and / or length of the frame element is increased.

The 'width' of the frame element is preferably the extent of the frame element in a horizontal plane (i.e. from left to right) when installed. For example, the width of the frame element is the extent parallel to the axis of rotation of the window that is mounted or can be mounted in the frame element. The 'length' of the frame element is preferably the height of the frame element (before it is installed) when vertically erected. For example, the length of the frame element is the extent of the frame element perpendicular to the axis of rotation of the window.

The 'opening' for installing the roof window device is a building opening that is to be closed by installing the roof window device. The opening is arranged on a roof or an overhead slope or end surface of a building. Preferably, the opening plane is an inclined plane with respect to the horizontal or vertical, so that after the roof window device has been installed, a horizontal roof window device is formed. The opening is delimited by a soffit, as further described herein (and which may, for example, be delimited laterally by rafters and above and below by alternating rafters).

A roof usually has rafters. To cover the roof, horizontal battens are laid on the rafters, on which the roof tiles are laid. When a roof window is installed, a corresponding opening is provided in the roof between the rafters and preferably in the width of the rafters. The roof window is usually inserted into this opening from the outside by several employees. When inserting, the roof window is mounted or screwed to the opening of the roof using metal sheets that run between the rafters or above and below the interchangeable rafters between the rafters (or the horizontal roof battens) and the frame element of the roof window device.

The holding elements enable easier, quick and efficient installation of a roof window. The roof window device or the frame element can be hung in an opening provided in a roof for assembly by means of the holding elements. Hanging can be done from inside the house or roof.

Preferably, the holding elements are hung on the rafters and more preferably at least two holding elements lie (at least during a partial assembly step) on the top side of the rafters from above on a roof batten. If the roof opening is not laterally limited by rafters (for example, if the width of the roof opening deviates from the grid dimension of the rafters) but by an opening frame construction, the holding elements are hung on the opening frame construction instead of on the rafters.

The frame element can be installed together with the assembled window without removing the window from the frame element for installation. Preferably, the roof window is pushed from the inside of the roof through the opening of the roof with the holding elements retracted and/or not swung out, that is, in a state in which the holding elements do not or substantially do not increase the width and/or length of the frame element until the holding elements are over the roof sticking out. The holding elements are then extended or pivoted out, so that the width and/or length of the frame element increases.

The frame element can then be released, with the frame element being held in the opening or on the opening reveal by the holding elements. In this case, the frame element can be aligned parallel to the plane that spans the skylight opening by the two holding elements after it has been extended or folded out (for example, if the two holding elements are two fold-out hinges as described below). Alternatively, the frame element preferably assumes a vertical position in the opening after being released by the fitter. The frame element can then be rotated until it is aligned parallel to the opening or the opening plane and held in this position, for example by extending another or several further holding elements.

Because the frame element is held in the opening and, as described above, it is not necessary to remove the window from the frame element, fewer employees are required for the entire assembly. For example, a frame element can be assembled by one or two employees. Since assembly is very simple in this way, assembly can also be carried out by unskilled and skilled people.

Due to the possibility of being able to carry out the complete assembly of the roof window from inside the roof, in contrast to the conventional assembly of roof windows from the top of the roof, no heavy equipment such as cranes or lifting platforms and/or scaffolding is necessary for the assembly of the roof window. In addition, less roof coverage (i.e. covering tiles at the opening) is necessary because employees do not have to carry out any work from outside during assembly. The resulting assembly advantages mentioned above also result in time and cost savings when assembling a window.

The installation is associated with little danger for both the roof window and the fitter, since the frame element is arranged in a fall-proof manner after hanging in the roof window opening by means of the holding elements for the entire subsequent assembly.

Preferably, the first holding element is arranged on a first side surface of the frame element and the second holding element is arranged on a second side surface of the frame element which is opposite the first side surface. Alternatively or additionally, the width and/or length of the frame element can be increased in opposite directions by extending and/or pivoting out the first and second holding elements.

The frame element preferably has inner and outer side surfaces. When the frame element is in a vertically arranged state, the side surfaces preferably run vertically or horizontally. The inner side surfaces rest on the installed window. The outer side surfaces are the side surfaces that are arranged on the frame element opposite the inner side surfaces. The holding elements are preferably arranged on the outer side surfaces, for example on the side surfaces that point in the direction of the length and/or the width of the frame element.

When extended or pivoted out, the first and second holding elements preferably extend parallel or substantially parallel to the width of the frame element. As a result, the frame element can be attached to a (soffit of the) opening in the roof for the skylight and in particular to the rafters and/or horizontally extending roof battens arranged around the opening in the extended or swung out state by means of the holding elements (or to an opening frame arrangement as described above). be hung. The rafters or horizontal roof battens hold the holding elements and thus the frame element with the roof window within the opening.

Preferably, the first and second holding elements are arranged in an end region of the frame element or in a region between the end regions of the frame element. The first and second holding elements can be arranged on opposite side surfaces that extend in the direction of the length of the frame element. Alternatively, the first and second holding elements can also be arranged on one of the side surfaces that extend in the direction of the width of the frame element and thereby extend in opposite directions.

Preferably, the first and second holding elements are arranged on the frame element in such a way that the frame element can be suspended from an opening for a skylight by means of the first and second holding elements.

Preferably, the roof window device has a third and/or fourth holding element, wherein the third and/or fourth holding element is arranged on the frame element in an extendable and/or pivotable manner, and wherein by pivoting out and/or extending the third and/or fourth holding element, the width and / or length of the frame element is increased.

The first and second holding elements can be designed to be extendable, for example as an extendable bolt, and the third and/or fourth holding element can be designed to be pivotable or foldable, for example as a hinge element.

Any number of additional holding elements can also be arranged on the frame element, which increase the width and/or length of the frame element by moving out and/or pivoting out.

Preferably, the first and second holding elements are arranged on the frame element in such a way that the width of the frame element is increased by pivoting out and / or moving out the first and second holding elements, and the third and / or fourth holding elements are arranged on the frame element in such a way that by pivoting out and/or extending the third and/or fourth holding element, the length of the frame element is increased.

Preferably, at least one holding element has an actuating element, wherein the holding element can be extended (preferably automatically) and/or pivoted out by actuating the actuating element. Preferably, the holding element is designed such that the actuating element interacts with the holding element in the retracted state of the holding element in such a way that the extending or pivoting out of the holding element is blocked by the actuating element. By actuating the actuating element, this blockage can be released and the holding element can be moved out or pivoted out (preferably automatically) (or pivots and/or moves out automatically).

For example, the holding element can be designed as an extendable bolt, the bolt being movably guided in a housing that is attached to the frame element. The bolt preferably has a recess into which the actuating element engages when the bolt is retracted and thereby blocks the bolt from moving out.

The actuating element is preferably designed as a lever which is rotatably mounted on the housing in which the bolt is guided. The lever is preferably biased by a spring element, whereby the lever is pressed against the bolt. As soon as the bolt is retracted so far that the recess on the bolt is arranged opposite the lever, the spring element preferably relaxes and presses the lever into the recess. This blocks the bolt from moving out until the actuating element is actuated.

For example, the holding element can be moved out or swung out manually by hand. Alternatively, when the holding element is retracted or not swung out, a spring element can be prestressed, with the spring element relaxing by actuating the actuating element and thereby moving the holding element (or the bolt out of the housing) or pivoting out.

The holding element can have a stop element which is designed to define a maximum extension position of the bolt. For example, the holding element is an extendable bolt and the stop element projects vertically or substantially vertically from the bolt. The stop element is preferably guided in a guide on the housing in which the bolt is guided, which is limited in the extension direction. This prevents the bolt from slipping out completely.

Preferably, the first and / or second holding element, preferably also one or more further holding elements, are designed as automatically retractable and extendable bars, which have at least one beveled sliding surface and are extended when the roof window device is inserted into the roof opening or into the reveal of the opening State can be transferred to a retracted state and automatically transferred to the extended state after passing through the opening or soffit. In particular, the holding elements are transferred from an extended state to a retracted state by the contact or the pressing of the holding elements against the reveal of the opening. For example, a spring is pretensioned on each holding element, which relaxes again after passing through the opening and thus returns the holding elements to the extended state.

Preferably, the first and / or second (or further) holding elements are designed in the manner of a door latch, which has a beveled sliding surface on one side, which leads to the retraction of the holding element when passing through the opening reveal, and which, after passing through the reveal, leads to a non-positive mounting of the Holding element on the top of the reveal leads as soon as the skylight device is stored on the top of the reveal by gravity.

Preferably, at least one of the holding elements is arranged on a side surface of the frame element and can be swung out or folded out, and the holding element has a locking element which defines a maximum pivoting angle or folding angle of the holding element of 90 degrees or substantially 90 degrees. Alternatively or additionally, the locking element is designed so that after the holding element has been pivoted out or folded out by 90 degrees or essentially 90 degrees, it blocks or prevents the holding element from falling below 90 degrees or essentially 90 degrees (i.e. a movement against the unfolding direction). This ensures that the frame element is held securely in the opening of the roof after the holding element has been pivoted out and the frame element cannot slip down through the opening by pivoting the holding element.

The maximum pivot angle ensures that the unfolded part of the holding element is arranged parallel or substantially parallel to the frame element. This ensures that the frame element is aligned parallel to the roof during assembly.

For example, the pivotable holding element can be designed as a sheet metal element that is connected to the frame element or the side surface of the frame element via a hinge.

For example, the locking element can be a separate element which, after the holding element has been pivoted out, can be inserted into the holding element in such a way that the swung-out part of the holding element is supported on the locking element, with the locking element in turn being supported on the frame element. This fixes the position of the swiveled out part of the holding element. The locking element is advantageously pre-assembled on the holding element.

Particularly advantageously, the locking element has locking elements which lock into place on the holding element when inserted and thereby fix the position of the locking element on the holding element after insertion. This means that the locking element cannot slip out and the pivoted out position of the holding element is ensured.

Preferably, holes or recesses are provided in the locking element, through which the locking element can be fastened to the frame element after insertion. This allows the rigidity of the device to be increased and the locking element to be secured.

For example, the holding element is arranged on a side surface of the frame element in such a way that it is folded from top to bottom during assembly, with the holding element being supported by gravity on the reveal of the skylight opening. In this case, the locking element prevents the holding element from moving against the unfolding direction (i.e. falling below 90 degrees is prevented).

Alternatively, the holding element is arranged on a side surface of the frame element in such a way that it is folded from bottom to top during assembly, with the holding element being supported by gravity on the reveal of the skylight opening. In this case, the locking element prevents the holding element from moving beyond the maximum folding angle of 90 degrees or essentially 90 degrees.

Preferably, the roof window device further has a first and a second sliding element, wherein the first sliding element connects the first holding element to the frame element, and the second sliding element connects the second holding element to the frame element, and wherein the first and second sliding elements are movable relative to the frame element by means of guides are arranged. The movability of the sliding elements makes it possible to vary the position of the holding elements on the frame element as desired.

The sliding element preferably has no sharp edges in order to avoid the risk of jamming when moving in the guides. The sliding element preferably has a length in the range of 80-120 mm, 90-130 mm, 100-140 mm or 110-150 mm. The longer the sliding element, the quieter and smoother the movement of the frame element with the window.

The sliding element is preferably made of plastic, preferably break-resistant plastic, such as a thermoset or gray cast iron.

The roof window device preferably has a first guide and a second guide, wherein the first guide for guiding the first sliding element is arranged on a first side surface of the frame element which extends along the length of the frame element, and wherein the second guide for guiding the second sliding element is arranged on a second side surface of the frame element which is opposite the first side surface , is arranged. In this case, the holding elements preferably extend in the extended state parallel or substantially parallel to the width of the frame element (ie the width of the frame element is thereby increased)

The guides for the first and second sliding elements preferably extend parallel or substantially parallel to the length of the frame element.

The guides for receiving the sliding elements can, for example, be integrated into the frame element, i.e. incorporated into the frame element using a tool. Alternatively, the guides can be mounted on the frame element as separate elements.

Preferably, the guides are designed to be open in the longitudinal direction at at least one end, so that the sliding elements can be inserted into the guides in the longitudinal direction. Particularly preferably, the guides are designed to be open at both ends and extend over the entire or substantially entire length of the frame element. This allows the sliding element to be inserted at one end of the guide and removed from the guide at an opposite end.

Preferably, a plurality of locking elements are arranged along each guide, with each locking element defining a predefined position along the guide, and with the sliding elements being designed such that by moving the sliding elements along the guide, the sliding elements can be locked in each of the predefined positions.

Each sliding element preferably has a recess in which the first and second holding elements, preferably a bolt, are arranged such that they can be extended. For example, the bolt can preferably have a hole or recess with which the bolt can be screwed to the roof during assembly of the frame element, for example to the rafters or horizontally extending roof battens.

Preferably, the bolt is rotatably mounted in the sliding element, so that the frame element can be rotated after the bolts have been screwed to the roof.

The sliding elements are preferably designed in such a way that movement of the sliding elements against a locking direction of the guide is blocked and/or prevented. “Locking direction” is the direction in which the sliding elements can be moved along the guide and can be locked into the predefined positions.

If the frame element is suspended from an opening in the roof by means of the holding elements and the holding elements are screwed to the roof, the frame element and thus the window can be moved from bottom to top by relative movement between the frame element and sliding elements. This allows the frame element to be aligned with the opening as desired.

Because the sliding elements do not allow any relative movement of the sliding elements on the frame element from bottom to top, the frame element is held securely in its position after hanging in the opening on the roof and cannot slip downwards.

Preferably, one of, several of or all of the sliding elements each has a release element, which is designed such that when the release element is actuated, the frame element can be moved relative to the sliding element against the latching direction. This makes it possible to lower the frame element in a targeted manner downwards when it is suspended in an opening in the roof via the holding elements.

Furthermore, a roof window arrangement is provided. The roof window assembly comprises: a roof opening with a reveal for receiving a roof window, and a roof window device as described herein, the frame element being suspended from the reveal of the roof opening by means of the holding elements.

The reveal of the roof opening, for example, is formed by rafters on the side and at the top and bottom by alternating rafters between the rafters. If the grid dimensions of the rafters cannot or should not be used, an auxiliary frame structure is inserted between the rafters (preferably made of wood), which then forms the reveal of the roof opening and in which the roof window device is mounted.

Preferably, by pivoting out and/or extending the first and second holding elements, the width and/or length of the frame element is each increased by at least 2 cm, preferably 3 cm, 4 cm or 5 cm enlarged. Alternatively or additionally, in the roof window arrangement, at least the insertion gap dimension between the frame side on which the first and/or second holding element is arranged and the inside of the opening is bridged by pivoting out and/or moving the first and second holding elements laterally from the frame element. The lateral extent preferably measures at least 1 cm, 2 cm, 3 cm or 4 cm more than the insertion gap dimension.

'Each' means that each holding element increases the roof window device by at least the specified width or length by swinging out to the side and/or moving out of the frame element.

'Insertion gap' is the gap between the frame element of the roof window device and the clear internal dimension of the opening through which the roof window device is inserted during assembly. Preferably, the gap is dimensioned such that the same gap is present on both or all sides of the roof window device.

Furthermore, a method for assembling a roof window device, in particular a roof window device as described herein, is provided. The roof window device has: a frame element, a window mounted or mountable in the frame element, and a holding device with a first holding element and a second holding element, the first and second holding elements being arranged on the frame element in an extendable and/or pivotable manner. The method includes: inserting the frame element into an opening provided for the frame element in a roof, so that the holding elements are arranged outside the roof and/or above the soffit of the opening, and hanging the frame element into the opening by extending and/or pivoting out the Holding elements so that the width and/or length of the frame element increases. Preferably, the frame element is suspended vertically or substantially vertically in the opening of the roof

Furthermore, the method can include: Aligning the roof window device or the frame element parallel to the plane that is spanned by the opening in the roof or the soffit, and fixing the roof window device or the frame element in the aligned position by moving out and / or pivoting out at least a further holding element (e.g. the third, fourth and/or fifth holding element as described herein).

Individual features disclosed above or below in this specification or in the claims may be claimed in any combination or sub-combination with one another. Features of the method can also be combined as functional features with features of the roof window device or the roof window arrangement as a single feature or in any subcombination of features. Conversely, features of the roof window device or the roof window arrangement can be combined with features of the method. Features of the method can also be combined with one another as a single feature or in any subcombination of features.

The insertion of a roof window device according to the invention may be necessary when renovating (i.e. replacing) an existing roof window or, for example, when inserting a new roof window into the building opening in a new building or when retrofitting an existing roof with a roof window.

1 shows a perspective view of a roof window device 7a suspended from a skylight opening 6. A roof 2 has the roof window opening 6, the roof 2 shown being formed by two inclined planes. The plane that is spanned by the roof window opening 6 lies in a plane that is oblique with respect to the horizontal or vertical. Thus, after installing the roof window device 7a, the roof window device 7a is arranged horizontally and preferably parallel to the plane of the roof window opening (and thus parallel to the roof slope on which the opening is arranged) (see also: 21 ). The roof 2 preferably has rafters (not shown). To cover the roof 2, horizontal roof battens 4 are laid on the rafters, on which the roof tiles are laid.

The reveal of the roof window opening 6 is formed, for example, on the side by rafters and at the top and bottom by interchangeable rafters between the rafters (not shown). Preferably, the roof window device 7a is attached to the rafters or as in by means of the first and second holding elements 10a, 10b 1 shown suspended on the horizontally extending roof battens 4 in the opening 6.

The roof window device 7a has a frame element 8 with a window mounted or mountable in the frame element 8, and a holding device with a first holding element 10a and a second holding element 10b. The first and second holding elements 10a, 10b shown are arranged on the frame element 8 in an extendable and/or pivotable manner. By extending and/or pivoting out the first and second holding elements 10a, 10b, the width (as in 1 shown) and/or the length of the frame element 8 is increased. Preferably, the width and/or length of the frame element 8 is increased in opposite directions by extending and/or pivoting out the first and second holding elements 10a, 10b.

In 1 the holding elements 10a, 10b are designed to be extendable and are shown in an extended state. By extending the first and second holding elements 10a, 10b, the width of the frame element 8 is increased. A preferred embodiment of such an extendable holding element is referred to 8th until 11 described in more detail.

The first and second holding elements 10a, 10b are preferably arranged on opposite side surfaces of the frame element 8. As in 1 shown, the holding elements 10a, 10b are each arranged on a side surface of the frame element 8, which extends in the direction of the length of the frame element 8 (ie left and right on the frame element 8). The holding elements 10a, 10b preferably extend in opposite directions and particularly preferably parallel or substantially parallel to the width of the frame element 8. As in 1 shown, the width of the frame element 8 increases in opposite directions (the in 1 Arrows shown indicate the extension direction of the holding elements 10a, 10b).

The roof window device is preferably pushed with retracted holding elements 10a, 10b from the inside of the roof 2 through the soffit or opening 6 until the holding elements 10a, 10b are arranged outside the roof. The frame element 8 is preferably arranged like this net that the width of the frame element 8 is arranged parallel or substantially parallel to the width of the opening 6.

The holding elements 10a, 10b can then be extended, which - as in 1 shown - the width of the frame element 8 is increased. By extending the first and second holding elements 10a, 10b, the width of the frame element 8 is preferably increased by at least 2 cm, particularly preferably by 3 cm, 4 cm or 5 cm, per side or holding element. The roof window device 7a can be suspended in a fall-proof manner by means of the extended holding elements 10a, 10b in the horizontal slats 4 arranged at the opening 6. The roof window device 7a is preferably suspended from the opening 6 or the corresponding slats 4 in such a way that the frame element 8 is aligned as desired in the opening 6 after pre-assembly, that is to say preferably has the desired distances from the opening 6.

2 shows a side view of the roof window device 1 in a first position and shown in dashed lines in a second position aligned with the roof window opening 6. The first position of the roof window device 7a corresponds to that in 1 position shown, ie the roof window device 7a is suspended from the opening 6, but is not aligned with the opening 6. The second position of the roof window device, which is in the 2 shown in dashed lines corresponds to an end position of the pre-assembly of the roof window device 7a. In this second position, the roof window device 7a is aligned with the opening or with the roof slope, with the length of the frame element 8 preferably being arranged parallel or essentially parallel to the roof slope of the roof 2 or with the length of the opening 6.

The roof window device 7a in the first position can be transferred from the first position to the second position by pivoting about the axis of rotation of the holding elements 10a, 10b. The rotation of the roof window device 7a is indicated by arrows on the frame element 8.

In order to fix the roof window device 7a in the second position, the roof window device 7a preferably has at least one third holding element 11a, which is arranged on the frame element 8, the width and/or length of the frame element 8 being adjusted by pivoting out and/or extending the third holding element is enlarged.

As in 2 shown, the third holding element 11a can be designed, for example, as a pivotable holding element, which is folded out or pivoted in the second position of the roof window device 7a (the unfolded position is indicated by an arrow on the holding element 11a). The unfolded part of the holding element preferably extends parallel or essentially parallel to the plane that spans the frame element 8. The third holding element 11a is arranged, for example, on a side surface that extends in the direction of the width of the frame element 8 (or perpendicular to the side surfaces on which the holding elements 10a, 10b are arranged). Alternatively, the holding element 11a can also be arranged on one of the side surfaces on which the first or second holding element 10a, 10b is arranged.

Preferably, the pivotable holding element 11a is designed so that after folding out it holds the frame element securely in its second position aligned with the roof. A preferred embodiment of a pivotable holding element and its functionality are described in relation to 12 until 14B described.

As in 2 shown, the roof window device 7a can also have a fourth and / or fifth holding element 11b, 11c to secure the frame element 8 in the second position. The fourth holding element 11b can be arranged, for example, on a side surface of the frame element 8 opposite the holding element 11a. The fifth holding element 11c can be arranged, for example, on one of the side surfaces on which the first or second holding element 10a, 10b is arranged. The fourth and fifth holding elements 11b, 11c are preferably also designed to be pivotable.

In the 3 until 7 The roof window devices 7b, 7c shown show further options for arranging the holding elements 10a, 10b and, apart from that, are very similar to the roof window device 7a in the 1 and 2 . Accordingly, only the differences to the roof window device 7a will be discussed below 1 and 2 described. All other features included in the 1 and 2 are described, are therefore also for the roof window devices 7b, 7c 3 until 7 valid.

3 shows a perspective view of a further roof window device 7b and suspended from the roof window opening 6 4 shows a side view of the roof window device 7b 3 in a first position and shown in dashed lines in a second position aligned with the roof window opening.

The holding elements 10a, 10b are arranged at a different position on the frame element 8 compared to the roof window device 7a. In 1 the holding elements 10a, 10b are arranged between the end regions 60a, 60b of a side surface of the frame element 8, in particular the side surface which extends in the direction of the length of the frame element 8. In the roof window device 7b the 3 the first and second holding elements 10a, 10b are arranged in relation to the length of the frame element 8 at a first, preferably upper, end region 60a of the frame element 8 (in the 3 at the upper end). In particular, the first and second holding elements 10a, 10b are arranged on a side surface which extends in the width direction of the frame element 8 (as in 5 shown). In the extended state, the first and second holding elements 10a, 10b extend preferably parallel or substantially parallel to the width of the frame element 8.

The roof window device 7b can thereby be suspended in a first position by means of the holding elements 10a, 10b at the first end region at the upper end of the opening 6 (preferably in contact with the side edges of the slats 4, which run transversely at the upper end of the reveal). The roof window device 7b suspended in the first position can be pivoted into the second position (end position) of the pre-assembly by pivoting about the axis of rotation of the holding elements 10a, 10b (see arrows in 4 and end position shown in dashed lines). By hanging the roof window device 7b at the upper end of the opening 6, the alignment of the frame element 8 with the opening 6 is made easier for the fitter. The roof window device 7b can be fixed in the second or end position as in the roof window device 7a 1 and 2 by further holding elements 11a, 11b, which are arranged on the frame element 8.

6 shows a perspective view of a further roof window device 7c suspended from the roof window opening 6, and 7 shows a side view of the roof window device 7c 6 in a first position and a second position aligned with the roof window opening (shown in dashed lines).

In the roof window device 7c the 6 are the first and second holding elements 10a, 10b in relation to the length of the frame element 8 at a second, preferably lower, end region 60b of the frame element 8 (in the 6 at the lower end), the second end region 60b being arranged at an end of the frame element opposite the first end region 60a. Preferably, the first and second holding elements 10a, 10b are arranged on a side surface at the second end region 60b, which extends in the width direction of the frame element 8. In the extended state, the holding elements 10a, 10b preferably extend parallel or substantially parallel to the width of the frame element 8.

The roof window device 7c can be suspended in a first position with the holding elements 10a, 10b at the second end region at the lower end of the opening 6 (preferably on the slats 4). The roof window device 7c suspended in the first position can be pivoted into the second position (end position shown in dashed lines) of the pre-assembly by pivoting about the axis of rotation of the holding elements 10a, 10b (see arrows in 7 ). By hanging the roof window device 7c at the lower end of the opening 6, the alignment of the frame element 8 with the opening 6 is made easier for the fitter.

The roof window device 7b can be fixed in the second position as in the roof window device 7a 1 and 2 by further holding elements 11a, 11b, which are arranged on the frame element 8.

Although in the 1 until 7 the first and second holding elements 10a, 10b are preferably shown as extendable holding elements (for example extendable bolts), the first and / or second holding elements 10a, 10b can also be designed as foldable holding elements, for example as a folding bolt or like the third, fourth and fifth holding elements 11a- c can be designed as foldable hinge elements. In this case, the holding elements can be swung out, the width of the frame element 8 being increased by folding out or pivoting out the holding elements.

Furthermore, the first and second holding elements 10a, 10b can also be arranged in such a way that when they are moved out and / or pivoted out, they do not move like in the 1 until 7 shown not only increases the width but also the length of the frame element 8. After moving out and/or pivoting out, the holding elements 10a, 10b preferably extend parallel or substantially parallel to the length of the frame element 8.

8th shows a side view of an exemplary embodiment of the first holding element 10a and/or second holding element 10b in an extended state. 9 shows another side view of the holding element 10a 8th . The holding element 10a has a bolt element 12 which is movably guided in a bolt housing 14. By extending the bolt element 12, the length and thus the length and/or width of the frame element 8 in the assembled state can be increased. The bolt element 12 preferably has a stop element 16 which is designed to determine a maximum extension position of the bolt element 12. The stop sel ment 16 is preferably guided in a guide 24, which is limited in the extension direction of the bolt element 12 (see 9 ). The bolt element 12 cannot therefore completely slip out of the housing 14. The stop element 16 can, for example, be a pin that projects vertically or substantially vertically upwards.

The bolt element 12 can be moved out manually by hand, for example by pulling on the free end of the bolt element 12, or by actuating an actuating element 20. Preferably, the bolt element 12 has a recess 22, with the actuating element 20 engaging in the recess 22 in the retracted state . interacts with this to prevent the bolt element 12 from moving out of the housing 14 (see 10 ). The bolt element 12 is preferably coupled to the interior of the housing 14 by a spring element 18a. When the bolt element 12 moves in, the spring element 18a is prestressed. When the actuating element 20 is actuated, the extension movement of the bolt element 12 is released and the bolt element 12 moves out by relaxing the spring element.

The actuating element 20 is preferably designed as a lever element and is rotatably mounted about an axis parallel to the longitudinal axis of the bolt element 12. Preferably, the actuating element is coupled to a spring element 18b, so that the actuating element 20 is prestressed in the extended state of the bolt element 12 and presses against the bolt element 12. When the bolt element 12 is retracted, the actuating element 20 is preferably brought into engagement with the recess 20 by relaxing the spring element 18b, so that the extension of the bolt element 20 is hindered or blocked in the retracted state.

The holding element 10a preferably points for attachment to the frame element 8 (see for example 1 ) a mounting element 26 attached to the housing 14 (see 10 ), for example a mounting plate. The mounting element 26 preferably has at least two holes or recesses, wherein the holding element 10a can be attached to the frame element 8 by means of fastening elements 28 such as screws.

12 shows a perspective view of a holding element, which is an exemplary embodiment of the third, fourth or fifth holding element 11a-c from the 1 until 7 and 21 corresponds. 13A shows a side view of the holding element 12 along the section line AA of the 12 in a folded state and 13B in an unfolded state. 14A shows a side view of the holding element 12 along the section line BB of the 12 in a folded state and 14B in an unfolded state.

The foldable holding element 11a is designed, for example, as a hinge element, which is in 12 is shown in the unfolded state. The holding element 11a has a folding element 42, which is movably connected to a connecting element 44 via a hinge 40a, 40b. The connecting element 44 is used to mount the holding element 11a on the frame element 8, in particular a side surface of the frame element 8, of the roof window devices.

The folding element 42 is preferably arranged in the folded state parallel or substantially parallel to the side surface of the frame element 8 on which the holding element 11a is mounted (see 13A and 14A) . In the unfolded state, the folding element 42 is preferably arranged perpendicular or substantially perpendicular to the side surface on which the holding element 11a is mounted (see 13B and 14B) . Preferably, the holding element 11a is designed such that a maximum folding angle is 90° or essentially 90°. The folding angle is preferably the angle that the side surface of the frame element 8 and the folding element 42 enclose between themselves. The folding element 42 preferably has holes or recesses for fastening to the roof 2 or the battens 4 to the roof 2 (see, for example, 1 ).

In the case of the foldable holding elements 11a-11c described here, these preferably also serve for the final assembly of the roof window. If, for example, four holding elements 11 a - 11 c are used at four different positions of the frame element 8 and the roof window device is pivoted into the position parallel to the roof slope and aligned with the reveal or opening 6, the swung-out folding elements 42 are with the material of the reveal and / or screwed to the roof battens. The reveal material is formed, for example, from the rafters running to the side of the opening and the upper and lower alternations. If the reveal is formed by an opening frame arrangement as described above, where are the holding elements attached to it. In the case of the extendable holding elements 10a, 10b, these can also be fixed or attached to the reveal in order to mount the roof window device in the reveal or opening. However, mounting elements are preferably attached to the reveal 6 and the frame element 8 from the top, which secure the roof window device in the reveal and also align the roof window device within the reveal in the final position.

Like for example in 12 shown, the folding element 42 preferably has a second projection 48 in the area of the hinges 40a, 40b, which extends counter to the first projection, ie downwards. The projection 48 preferably serves to be able to easily fold out the folding element 42 from the inside of the roof when assembling a skylight device. Alternatively or additionally, the projection is designed to be supported on the frame element 8 in the unfolded state, and thereby preferably to limit the folding angle to 90° or essentially 90°.

Preferably, the hinge 40a, 40b is interrupted by a projection on the folding element 42, which preferably projects vertically or substantially vertically from the folding element 42, and is divided into two individual hinges 40a, 40b, each hinge 40a, 40b having a connecting element 44 for mounting on the Frame element 8 has. Preferably, the holding element 11a shown is mounted on the frame element 8 in such a way that in the pre-assembled state of the roof window devices 7a-c, the projection 46 projects outwards or upwards at the roof window opening 6 in the unfolded state of the folding element 42 (see 13B) .

The holding element 11a preferably has a locking element 50 or a locking bolt, which is designed to block the movement of the folding element 42 against the unfolding direction (ie the movement in the direction of the folded state) in the assembled state. This allows a roof window device, for example the roof window device 7a 2 In the second position, ie the roof window device is pre-assembled in the roof window opening 6 in a fall-proof manner parallel to the plane of the roof window opening 6.

The locking element 50 can be designed, for example, as an angle element, which - as in 13A and 13B shown - can be inserted from below (or from the inside of the roof) between the projection 46 and the frame element 8 in the unfolded state of the holding element 11a.

Preferably, latching elements are provided on the locking element 50, which prevent the locking element 50 from slipping out again after being inserted between the frame element 8 and the projection 46. Furthermore, holes or recesses can be provided on the locking element 50 in order to firmly connect the locking element 50 to the frame element 8 after insertion.

The locking element 50 can have a pre-assembly element 52, which serves to pre-assemble the locking element 50 on the holding element 11a, and in particular between the two hinges 40a, 40b. As a result, the locking element 50 is pre-assembled on the holding element 11a and cannot be lost. In addition, this makes it easier for the fitter to insert the locking element 50 to lock the holding element 11a.

15 shows a perspective view of another roof window device 7d, and 16 shows a side view of the roof window device 15 . In contrast to the roof window devices 7a-c, the roof window device 7d has a first and second sliding element 54a, 54b. The first sliding element 54a connects the first holding element 10a to the frame element 8 and the second sliding element 54b connects the second holding element 10b to the frame element 8. The sliding elements 54a, 54b are each arranged to be movable relative to the frame element 8 by means of a guide - see 17 .

As shown, the frame element 8 preferably has a first guide 56a for guiding the first sliding element 54a and a second guide 56b for guiding the second sliding element 54b. The first guide 56a preferably extends along a side surface of the frame element 8, which extends along the length of the frame element 8. The second guide 56b is preferably arranged on a side surface of the frame element 8, which is arranged opposite the side surface of the first guide 56a.

Each of the two guides 56a, 56b points as in 16 shown a plurality of locking elements 58, which are arranged along the longitudinal axis of the guides and define a plurality of predefined positions. The sliding elements 54a, 54b are designed such that by moving the sliding elements 54a, 54b along the guides 56a, 56b, the sliding elements 54a, 54b can be locked in any of the predefined positions. As a result, the sliding elements 54a, 54b can be moved from top to bottom relative to the frame element 8 with respect to a vertical orientation of the frame element 8 (see arrow in 16 ). The sliding elements 54a, 54b are preferably designed in such a way that a movement of the sliding elements 54a, 54b counter to a locking direction of the guide 56a, 56b (ie in 15of bottom to top) is blocked or prevented. The sliding elements 54a, 54b can each have a release have element which is designed so that when the release element is actuated, the frame element 8 can be moved relative to the sliding element 54a, 54b against the latching direction.

The holding elements 10a, 10b are preferably designed to be extendable, for example as bolts as in 18 shown. The holding elements 10a, 10b are preferably rotatably arranged in a recess on the sliding elements 56a, 56b. As in 18 As can be seen, the holding element 10b preferably has a first stop 62a, which limits the movement of the holding element 10a in the extension direction (ie increasing the width of the frame element 8). The holding element 10b preferably has a second stop 62b at an end of the holding element 10b opposite the first stop 62a, which limits the retraction movement of the holding element (ie counter to the extension movement). The holding element 10b cannot therefore be lost. Furthermore, the holding element 10b can have a fastening recess 64, which is designed to fasten the holding element 10b to the reveal of the roof opening or to the rafters and/or roof battens. The configurations for the holding element 10b are also valid for the first holding element 10a.

Preferably, the holding elements 10a, 10b are in a retracted position (as in 15 shown) arranged above the frame element 8. Particularly preferably, in a retracted position, the holding elements 10a, 10b do not or substantially do not protrude laterally beyond the width of the frame element 8. The holding elements 10a, 10b can be extended in opposite directions parallel or essentially parallel to the width of the frame element 8 (see arrows in 15 , 17 )

Below we will do so within the framework of the 19 until 21 a preferred sequence of pre-assembly of the roof window device 7d, which is shown in the 15 until 18 is shown, described.

The roof window device 7d is pushed with retracted holding elements 10a, 10b from the inside of the roof through the opening 6 until the holding elements 10a, 10b protrude from the roof over the opening or are arranged above the reveal of the opening 6 (see 19 ). Next, the holding elements 10a, 10b are extended so that the width of the frame element 8 increases (see arrows in 19 ). The frame element 8 is then preferably hung on the rafters with the holding elements resting on the roof battens and the holding elements 10a, 10b are then preferably fastened to the roof (preferably by means of the fastening recess 64 in 18 ). The frame element 8 is preferably aligned vertically due to gravity.

The frame element 8 can then be moved upwards as desired, with the sliding elements 54a, 54b moving downward along the guides 56a, 56b (see arrows in 20 ). After the desired position has been reached, the frame element 8 can be aligned parallel to the plane of the opening 6 by rotating about the axis of rotation of the holding elements 10a, 10b (see 21 ). The frame element 8 is then preferably moved out and / or pivoted out further holding elements 11a-c, for example folding holding elements as in 12 until 14B shown, fixed in the position parallel to the opening 6. The holding elements 11a-c can have recesses that can be used for final assembly, ie for fastening to the roof 2.
